WIRE STRETCHIER.

To all whom it may .t-onemn:

Be it known that I, lsrnn F. LOUY, it tizen of the United States,residing ut Seattle. in the county of King and State of Washing:- ton,have invented. certain new and use'l'ul Improvements in.Vire-Strrvteliers, of which the following is a specification, referencebe ing had therein to the accompanying drnwlngs.

This invention relates to wire-strelohers; and especially to that classwhich are-eniployed in handing boxes of merclmndise or the like.

The principal object of the invention is the provision ol an ellicientimplement of this nature which will he of relativelylig ll weight,convenient to luntdle and powerful in notion.

A further ohjeet is to produee an ill] Inent .l'ul'lilling' the aboveehameteristirs, which will be of simple and inexpensive eonstruotion andthe mrts thereof so proper tioned and disposed that it will he durathleand not readily deranged end suited to witlu stand the rough usages towhich sueh devices are subjected.

WVith these ends in View, the invention consists in the noveleeustriwtion, zidnptntion and combination of nnrr as will he 1n thedrawings, Figure l is :2. perspective View of o Wire stretcher embodyingmy invention, Fig. 2 is av side elevation ol' the some with portionsbroken away; Fig. 3 21 hire view ti oof; and Fig, 4 is a fragmentaryView of the smile.

The it 'erenre numeral 5 designates :1 her which desirably rectangularin eross section erul is provider l at one end with it lruusverseiysinged curved plot-e 1'5 with the concna nice 6 thereof outermost to:tllOHl :2 breast support for the operator's body. At the other end thesides of the lmr are cut away, or the her is formed, to t'urnish nprotrading tongue 7 and extending longitudinally thereof from theextreme end and for some distance it )on the body ol' the bar and uponthe face side is a groovefi, while notehes 9 are provided. in the rearof the her and extending from each side ot the tongue, :is shown in Fig.4. Intermediate the length of said bar it provided with forwardly extendin eats 10 which are most eonveniently forms upon it separate iieeeformed with n central portion 10 whioi is urrunged to he rivet-ed, orotherwise reliably secured to the.

lu'ir. 'lhese ears are sport-tired, as it 11, t0 nll'ord journalhearings l'or a rod 12 which is bent at the right-luuul side to furnishs eronk-lutndle l2. ltigidlv connected tothe rod end hetween thenioresuid ears is a toolhed-wheel, or pinion, lii'which is in continuousmesh with the teeth 14 of a rocklmr H slidnhly is retained in ulineinonttierewith by said ears and the provision of :1 block 14 integral withthe bar 1-4 and in proximity of its lower extremity, and which block is:1 iertured, as at 15, so its to arr-onzinodztte the. her 5 with asliding lit. To this rut-lobar and adjacent oi the lower extremity, usupon said block, is n wire rlzuuping device comprised, desirably, of astationary jaw l6 and it dog 17 which is pivoted to the ratchet-hinby abolt 18. The opposing lures H3 and 17 ot the jaw and dog are serrnted tosllord no eleetive grip upon the wire which is to he stretched.

'lhe operzitiolil ol the invention may he explztined as follows: Thewire 20, which is provided with. :1 loop 20 st one end, is first pussednhont u ooi; and its other end .20 threuded throuqh said loop. "lhetongue 7 is then inserted though the wire loop so es to engage with thelie); and the end 20 o wire introduced be tween the jaw 16 and to dog 17when the rank carrying these elements is positioned at the end of itstravel townrd the bur-tongue. A -linger pressure exerted upon thedog-handle 11 will silent the dog to ehnnp the wire and is thusmeintnined until it tension is put upon the wire through the reeedeneeof the rack-hm hy turning the handle I .5 and through the olliee oi" thepinion i3. ri'hen the wirehss hen properly stretched by the eoi'itinuedturning of the. urin'ik-luindle. the implement is then tilted forwardlyto bend the wire part 20 into ll. hight about the loop, end theimplement "inny then he disengaged by the release he ,dog 17 through acontrary movement of the operntofls lingers upon the dog-hnni'lle l7.''lho referred to bight of the wire is then made more acute by strikingthe some with the edge of the plute 6 ein loyed as at hztnuner with theher 5 serving as the handle tl'iereot'in such :ietion. The operation. ofwire stretehingris thus eonupetiul and the tree end o the wire, that is,the, pert 20 is then roi d shout the nrti'n portions hv' Miler devieeswhir'h have notliiiu; to do with the present in vention.

mounted [1.7011 the bar 5 and v In banding boxes, the implement wouldordinarily be grasped by the left hand and the dog actuated by the thumbof this hand while the right band would operate the crank-handle toaccomplish the stretching of the wire. Ordinarily such holding of theimplement would be all that is required, but in exceptionally heavy workthe operator s body is brought tobear against the plate 6.

The provision of the groove 8 serves to lead the free end of the wire ina straight line from the point of the tongue to the clamping devices,and the groove 9 take the wire of the loop and permit the bar 5 to bebrought into close relation with the box to be'banded.

What I claim as my invention, is-

1. An implement of the class described comprising a bar provided at oneof its ends with a rotruding tongue having a groove on one s1 eextending into the bar, a rack-bar slidably connected with the aforesaidbar,

inion supported by the first named bar and in continuous mesh with therack-bar, means for rotating said pinion, and wire clamping meanscarried bythe rack-bar the wire being received in the groove in saidtongue and bar.

2. An implement of the class described comprising a bar provided at oneof its ends with a protruding tongue grooved longit: dinally on oneface, the groove extending into the bar, a rack-bar slidably connectedwith the aforesaid bar, a "nion supported by the first named bar and 1ncontinuous mesh with the rack-bar, means for rotating said pinion, wireclamping means carried by the rack-bar and comprised of a fixed jaw anda dog the said groove in the tongue and bar receiving I provided saidwire.

3. An implement of the class described comprising in combination, a barprovided at one end with a tongue and at the other end with a breastplate, the tongue being grooved longitudinally on one face and the arbeing on the opposite face at the base of the tongue with notches anattachment fixedly connected with the bar intermediate the length of thelatter, a rack-bar slid ably mounted upon the first named bar, a pinion,a rod provided with a c1-ankhandle and carrying the union, said rodbeing journaled in said attachment, a serrated jaw fixedly connectedwith said rack-bar, and a serrated dog pivotally connected with saidraeka1.

4. In an imp the combination with a bar having a protruding tongue atone end, said bar being provided 11 n one of its faces with a grOQve 1extending om the point of said tongue to some distance therefrom uponthe bar, an being also provided upon the opposite face 1 with. twonotches disposed upon the opposite 1 sides of the tongue, and aperturedears extending from said bar; of a crank-rod extending through theapertures of said ears, a pinion fixedly mounted u on the rodintermediate of the cars, a rack ar slidably mounted upon the firstnamed bar and having its teeth engaged by said pinion, a jaw fixedlysecured to the rack-bar, and a dog ivotally connected with the raclebarand a apted to cooperate with said jaw.

5. In an implement of the class described, i the combination with a barhaving a curved breast plate at one end and a protruding tongue at theother end, said bar being provided upon one of its faces with a grooveextending from the point of said tongue to some distance therefronr uponthe bar, and being also provided upon the opposite face with two groovesdisposed upon the opposite sides of the tongue, and apertured earsextending from said bar; of a crank-rod extending through the aperturesof said bars, a pinion fixedly mounted upon the rod intermediate of theears, a racl -bar slidably mounted upon the first named bar teethengaged by said pinion, a block inclosing the first named bar andintegral with the rack-bar, ajaw fixedly secured to the rackbar, and adog ivotally connected with the raclebar and at said jaw. v

In testimony whereof I afiix my signature in presence of two witnesses.
